3 Claims.

5. of uniformly arranged laths, reeds or of other material, used for such or similar purposes, which will enable the workman in securing the lathing in place while it is being attached to the studding or the ceiling beams of a building.

Lathing structures of similar nature are not new, however, their construction is either not very practical or too costly, and possesses a great many disadvantages which are objectionable from the standpoint of weight, difiiculties in *i the manufacture and costliness, coupled with unevenesses in the spacing required oetween the individual laths, reeds or the like.

A further disadvantage resides in the fact that most lath sheets can not be stored foran appreciable length of time Without being detriinentally affected, particularly in respect to their connecting means, by dampness or other in1iuences, whereby their usefulness is seriously impaired.

The present invention is designed for overcoming all of the above disadvantages and it's'principal objects are to provide a laths construction which not only will be considerably less expensive than any heretofore produced devices of this kind, but which has the advantageous features of eing extremely flexible, light in construction,

durable during the period of storing it, irrespective of the length of storing time, and in which the spacing of the individual laths, reeds or the like will be absolutely uniform, and remain so when the sheets are rolled up into bundles or stored in any other manner.

The prime characteristics of this invention reside in the formation of a laths construction whereby a single laths connecting member is employed between the individual laths, which is emdividually secured to each lath by suitable attaching means, comprising either staples as such, or stapling means forming integral parts of and made from the connecting member itself.

Another object of my invention is the method or manner by which the connection of the individual laths and their spacing is effected.

The foregoing and still further objects will be-- come more fully apparent from the following de scriptions and the accompanying illustrations,

forming part of my disclosure. out by no means,

intended to limit my invention to the actual showing, and in which Figure 1 illustrates one of the forms of laths Serial No. 544,330 (Cl. 72-116) construction, at present preferred, illustrating an arrangement of individual laths staggered relative to one another.

Figure 2 isan enlarged perspective detail view illustrating my invention.

Figure 3 is a cross-sectional view through Fig ure 2, taken on line 33 of that figure.

Figure 4 is a longitudinal cross-sectional view taken on line 4-4 of Figure 2.

Figure 5 is a diagrammatical illustration of the manner in which my lath construction is effected.

Figure 6 illustrates a modified arrangement of my lath construction, and represents a sample intended to show the variations possible in the arrangement of laths groups in staggered relation to one another. a

Figure 7 illustrates a modified form of attaching a lathe connecting member.

Figure 8 illustrates another modification of my laths construction in which the laths connecting member is employed not only for connecting of the laths, but also for providing attaching means for the lath, and

Figure 9 illustrates another modification of a one-piece laths connecting and attaching arrangement.

Referring now to the figures, numeral 10 denotes individual laths which are arranged in staggered relation to similar laths 11. These laths are held together by means of two parallel p ble wires 12, which are secured to the in d dual laths by means of staples 13. The la ter are driven into the lath material with suf ficient force so as to cause wire 12 to be crimpe by staple 13 as indicated at 14. The crimping cf the wire into the lath material provides an interlocking connection and a check for the movement of; the wirerelative to the lath, whereby'the spacing between *the lath is caused to remain permanent. Furthermore, the thriving of the staple deeply into the lath material cures them against uninadvertently up. 7

Referring to Figure 7, a lath 15 is shown to which is attached wire 16 by means of a of staples 17, in which case the staples are driven by force in the same manner shown described in connection with the previously described arrangement, but in which the staples are longer than the thickness of the lath material, so that the pointed ends 18 of the are curved or hooked into the lower face of the lath.

Such arrangement obviously may be employed loosening also in connection with the illustrations shown in Figures 1, 2, 3 and i. As will be seen from Figure 7, wire 16 is also forced into the lath material through the attachment of the staples thereto, whereby the wire is crimped, as indicated at 19. Thus a very rigid attachment of the wire to the lath material is provided in two places on the upper surface, while the staples are prevented from disengaging the lath by the formation of hooks 18 from the sharp staple ends, which latter penetrate the lath material at its lower surface.

In Figure 8 laths 20 are shown over the upper surface of which runs a metal strip 21, from which triangular prongs 22 are blanked out and serve, in place of the individual staples em ployed in the aforesaid described constructions, for fastening of the strip.

These prongs are preferably of such a length that they penetrate the lath material and are thus capable of engaging their lower surface by their sharpened ends which are turned upon themselves into the lath material, as indicated at 23, in similar manner as described inconnection with the long staples shown in Figure 7.

A similar construction is illustrated in Figure 9, where again a lath member 24 is illustrated, over which passes a metal strip 25. In this case side prongs 26 are formed from the strip material and are also preferably longer than the thickness of the lath, so as to penetrate the lath material. The sharpened ends 27 of the prongs are bent upon themselves and into the lower face of the lath material so as to securely hold the strip and lath together.

In Figure 6 there is illustrated a modified grouping of the laths where a triple arrangement of lath groups 28 is staggered relative to lath groups which groups are held together by wire or strips 33 secured to the individual laths of each group.

The coimection of the individual lath, whether in groups, or whether staggered or arranged with their ends in line, is preferably accomplish by a suitable device, illustrated diagrammatically in Figure 5. In this figure a cylinder 31 is shown provided at its periphery with longitudinally arranged. blocks 32, which serve as spacers between the individual laths.

A stationary, cylindrically formed guard or guide 33 surrounds the cylinder and its spacers for holding the individual laths against the cylinder when placed into the longitudinal openings formed between spacers 32. The individual laths are placed into those openings at the left hand portion of the cylinder, just above the left hand end of lath rest 34 of the guard or guide As the laths are thus inserted between the spacers, cylinder 32 gradually travels in anticlock wise direction until all the lath receiving openings are completely filled; When the laths finally reach the top of the cylinder, wire 35, running transversely over the lath, is stapled down by means of a plunger, indicated at 36, to which the necessary number of staples, indicated at 3'7 are fed at the same speed as the laths gradually reach their upper-most position. The stapling operation results in drawing of portions of the wire into the laths material.

Once stapled, wire 35 which is running in left hand direction, takes with it the attached lath member, and the lath construction is thus ready to be rolled up into bundles for shipment.

The above described manner of stapling will of necessity undergo some changes, when either two staples are used in fastening the wire, described in connection with Figure '7, or when strips are prepared for connecting the lathing, as described in connection with Figures 8 and 9. Since such changes are obvious, I do not feel the necessity of specifically illustrating them, it being understood that when metal strips are used, the prongs provided from those strips for the purpose of attaching them to the lathing must be punched out, prior to the time of reaching the lathing.

It is further obvious that various changes in the grouping of the lathing may be arranged, and the method of stapling or attaching the connecting members to the lathings may be altered in the course of refining the methods of manufacture to higher efficiency.

I therefore reserve for myself the right to make changes and improvements within the broad scope of my idea, as set forth in the annexed claims.

I claim:

1. In a continuous lath construction, the combination with a series of parallelly arranged, uniformly spaced laths, at least two parallelly arranged, continuous lath connection members disposed substantially at right angles to and attached at one face of said laths, attaching means securing said connecting members to said laths, said attaching means adapted to so interengage with said laths and said connecting members, as to not only draw portions of the latter into one face of the material of saidilaths, thereby preventing a movement of said connecting members relative to said laths, but to also th mselves penetrate the lath material and to engage with their protruding ends the opposite face of the laths, in which the ends are anchored for preventing the disengagement of said means from said laths.

2. In a continuous lath construction, the combination with a series of parallelly arranged, uniformly spaced laths, at least two parallelly arranged, continuous lath connecting members disposed substantially perpendicularly to and attached at one face of said laths, attaching means for said connecting members in the form of staples, the latter straddling said connecting members and forcing portions thereof into one face of the lath material, the prongs of said staples passing through the body of the lath material and being turned upon themselves and into the opposite face of the lath material, for the purpose specified.

3. In a continuous lath construction, the combination with a series of parallelly arranged, uniformly spaced laths, at least two parallelly arranged, continuous lath connecting members disposed substantially perpendicularly to and attached at one face of said laths, attaching means for said connecting member in the form of staples disposed substantially remote from the edges of the laths, said staples straddling said connecting members and forcing portions thereof into one face of the lath material, the prongs of said staples passing through the body of the lath material and being turned upon themselves and into the opposite face of the lath material, for the purpose specified.
